WPA is the precursor to WEP and filled a need as a replacement for the fully disclosed and unsecure WEP encryption.

For an excellent explaination, see the Airolib-ng manual.

pyrit blog - Reference manual - Code details
- Like coWPatty and Airolib-ng
- Pre-compute PMK keys
- Internal database over precomputed ESSID and PMK combinations
- Can export to *.cow (coWPAtty) and *.db (Airolib-ng)
- GPGPU acceleration
- Strip out 4-way handshake from capture file

coWPAtty Main page - coWPAtty project page - Readme
- Like Pyrite and Airolib-ng
- WPA-PSK attack on specific ESSID and captured 4-way handshake dump
- Passthrough from Pyrite possible (GPGPU acceleration)
- Pre-computed PMK tables supported
- genpmk:
  - Generate "Pairwise Master Key" table for a specific ESSID, PMK tables
  - Table-file name should end with *.cow

Airolib-nb
- Like coWPatty and Pyrit
- Precompute TMK keys and attack WPA/WPA2 handshake captures
- Internal SQLite3 database
- Can export and import coWPAtty files

Extra:

Church of Wifi wpa-psk rainbow tables
- Pre-computed TMK key tables, 1 million words computed for the top 1000 SSID's
- 7 and 33 GB torrents
- Hak5 single tables downloads

These are compiled word lists and readily available.

Church of Wifi wordlists - passwords2 (2.1 MB) and 9-final-wordlist (11 MB)
Outpost9.com (direct) - dic-0294 (8.04 MB) (reference)
Openwall wordlists - Multiple languages, small fee
The Argon various wordlists - There are WPA versions of these lists, see Xploitz below
Xploitz Master Password Collection
- Huegel's Cracking Dictionary Compilation - Cleaned-up version of Xploitz list

Following simple guidelines, a good word-list can be generated. Consider the following:

Most people use easy to remember passwords, in this case it has to be 8 characters or over in length
Append 0-9 to the word, i.e. (word)1, (word)2, (word)3, ..
Sequence of numbers are often used, e.g. 123, 321, 999, ..
First letter is often upper-case
Short words (under 8 characters) are stringed in series of two, e.g. googlegoogle, hellohello, openopen, ..
Forename and surname often used
